420A No spark 96 Eclipse

[acrheam]

I have a 1996 Mitsubishi Eclipse 2.0 Non-Turbo. I bought this car from a "mechanic" he said the car came in with a broke timing belt and he put a new timing belt on, but he didn't set the timing right, I got the car, put all new valves in it because they were bent. Put the head back together and set the timing, car isn't getting any spark. It's getting gas. The car cranks over but won't fire. If anyone knows where I should start at, I don't know if I should just throw new parts at it or what. I took it down to a garage by where I live, they hooked it up and it said camshaft sensor was bad, they put a new cam shaft sensor in it and still nothing. I need some steps to go by or something. Any help would be appreciated. Thanks!

if its spark pull a spark plug out and hook it up to the spark plug wire have a friend turn the motor over and watch for a spark at the plug check all four if no spark test coil packs and replace as needed. make sure the plugs aren't fouled.

I'm not familiar with the 420a, but does it have a crank sensor as well as a cam sensor? If so, I'd check that too. It would most certainly keep the car from starting.

Do you know what the coil pack should read? I just tested mine and it reads
1 and 4 = 11.4 (tested at 200k ohm)
2 and 3 = 11.4 (tested at 200k ohm)
Also tested where the connector goes = .8 (tested at 200 ohm)

I was also thinking the crank position sensor was bad if this isn't the problem, how would I test that?

I'll have to check my service manual tomorrow to let you know, but it would be similar to how you checked the coils and CAS. I can't remember the resistance off the top of my head.

It does have both crank and cam

1. Disable spark (if there is any). Hold accelerator to floor and crank engine, listen carefully for even rotation. A fast spinning cylinder indicates a mechanical problem resulting in a low compression condition. This is how I would quickly check for a mechanical problem .
2. Crank sensor uses a hall effect type, the sensor/wiring could be the culprit. Voltage (Vref), ground, and signal. I prefer to disconnect the sensor and attempt to light a small bulb (194) using my suspect circuit. If you can ground your bulb thru the vehicle harness, no open is suspected. (this allow you to rule out a corroded/hogged out ecu connector)
3. It should make a square wave. If the circuit checks out, and it cannot create a usable signal, the sensor is faulty. Spark timing requires accurate crankshaft position to the degree. Best of luck.

Coils are notorious for going out on the 420A
